ABSTRACT:
A sheet metal enclosure is used for spray painting automobiles and for heat curing the paint. A fan draws filtered air through the enclosure. An air supply permits spray painting. Quartz tube radiant heaters are mounted flush with the interior walls of the enclosure for heating the painted vehicle. A safety interlock prevents simultaneous enablement of the sprayer and heaters. Further, there is a first time delay before the air supply is enabled to assure that the heaters are cool before spraying paint, and a second time delay before the heaters are energized to permit the fan to exhaust paint fumes before applying heat.
